Analog To Digital Converters (ADC) Procurement Notes

Verify the component authenticity by checking for the 'LTC2145UP-14' part marking on the device surface. Confirm the lead-free finish designation '#PBF' matches the order information table. Ensure the operating temperature range corresponds to the 'C' suffix (0°C to 70°C) as specified in the datasheet ordering section.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring high-speed digitization of wide dynamic range signals. The LTC2145-14 variant supports up to 125Msps; consider the LTC2144-14 (105Msps) or LTC2143-14 (80Msps) if lower power consumption is prioritized over maximum sampling speed. Ensure the system clock duty cycle stabilizer is utilized if the input clock duty cycle varies significantly.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2145-14/LTC2144-14/LTC2143-14 family of low-power dual ADCs. The 'C' suffix denotes the commercial temperature grade (0°C to 70°C), while the 'I' suffix indicates the industrial grade (-40°C to 85°C). The 'UP' indicates the 64-lead QFN package type.
